FURNACE.

Specification of letters Patent.

Patented Jan. 18, 1921.

I Application filed'June "-11, 1919. Serial no. 303,336.

To all whom it may concern:

Be it known that I, GEORGE W. Howns, a citizen of the United {States,residing at Dowagiac, Michigan, have invented certain new and usefulImprovements in Furnaces, of which the following is a specification.

This invention relates to improvements in furnaces.

The main object of this invention is to provide an improved furnacewhichmay be adjusted to face asdesired, and direct chimney connectionsfrom the radiator maintained.

Further objects, and objects relating to structural details willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention isclearly'defined and pointedout in theclaims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawin s forming a part of thisspecification, in w ich:

Figure I is a side perspective view of a structure embodying features ofmy invention parts only of the casing being shown.

Fig. II is a detail plan view of the lower section of the radiator.

Fig. III is a plan view of the base.

Fig. IV is an enlarged detail horizontal section on a line correspondingto line ie-4 of Fig. I.

Fig. V is a detail side perspective showing the radiator adjusted to aposition at right anglesto its position in Fig. I.

Fig. VI is a fragmentary detail plan view with the upper portion of theradiator removed, parts of the casing being shown in section. i

Fig. VII is a detail section on a line corresponding to line 7-7 of Fig.VI.

Fig. VIII is a side perspective view with the outer casing removed.

In the drawings, similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawings, the furnace body in the structure illustratedis formed of sections 1, 2, 3 and 4, section 1 being the ash pit sectionand the sections 2, 3 and 4 forming the fire pot and combustion chamber.The base 5 is designed to receive the extension ltdisposed oppositely.The front wall 15 is provided with an opening 16 with whlch theclean-out 1.4 may be brought into 7 re ister.

The front wall is securedto the ash pit and the fire pot passages bymeans of bolts 17 arranged through lugs 18 provided on these passages.The front wall is provided with "forwardly projecting flanges 19 towhich-the outer casing 20- is secured by bolts 21. The inner casing 22is double walled in the structure illustrated, its lower edge be ingmounted on thefring 23 supported by uprights 24 on the base bars 7.

The inner casing members have lapping flanges 25 which overlap theflange 19, these casing membersbeing supported by the eye bolts 26engaged on the inner ends of bolts 17 which secure the front wall to thefurnace body, the bolts 17 being provided with nuts 27 on the innersides of the lugs and nuts 28 to retain the eye bolts.

The furnace illustrated is one of the one register type, the registernot being shown, as such registers are known in the art and form no partof this invention. It is sufiicient to say that the connections are madeso that the air circulates downwardly in the outer casing and upwardlyabout the furnace body and radiator.

To permit the positioning of the furnace in its most convenientrelation, that is to provide for facing it without regard to thechimney, the radiator is arranged so that it maybe mounted in differentpositions relative to the body. This I accomplish by providing the base5 with a series of lugs 29 and the radiator with a plurality of lugs 30adapted to be brought into vertical alinement with the lugs 29, so thatthe tie bolts 31 may be engaged therewith. These tie bolts are centered,that is their pull is cen tered without regard to the adjustment, sothat they serve not only to hold the radiator in place, but to clamp thefurnace sections together, thereby avoiding the necessity for separatelybolting the several sections together and clamping them together so thatthe joints do not open under expansion or under the shocks of suchexplosions as are likely to occur on account of the accumulation of gas.

I have not illustratedthe particular form of joints for sections, assuitable nesting and seating joints are known in the art. In Fig. I, Ishow the radiator with its clean-out registering or connected to theopening 16 in the front wall. In Fig. VI, I show it disposed at rightangles to the position shown in Fig. I. When thus arranged I provide aclean-out extension 32 which is disposed be tween the inner and outer,casing members,

and secured to the flanges on clean-out 14 by bolts 33, a gasket 84being arranged between the flanges to provide a secure joint at thispoint. The extension 32 projects through the outer casing and isprovided with a door or cover 35.

My improved furnace is designed so that it may be shipped knock down andset up or assembled at the place of installation by an unskilledworkman. This is particularly feasible where my improvements are embodied in a one register furnace as illus trated. However, certain of myimprovements areadvantageous for use in other types of furnaces. I havenot attempted to illustrate ordescribe such other adaptations orembodiments as I believe the disclosure made will enable those skilledin the art to which my invention relates to embody or I claim as new anddesire to secure by Letters Patent is:

1. The combination of a furnace body having a plurality of spaced tiebolt holes, a front wall secured to said furnace body and having aclean-out opening therein, an annular radiator seated on said body andhaving a smoke flue and a clean-out extension adapted when said radiatoris adjusted to one position to register with said front wall clean-outopening, said radiator having a plurality of tie bolt holes disposed toaline vertically with the holes on said body with the radiator indifferent adjusted positions relative to the body and, tie boltsengaging alincd holes of said body and said radiator.

2. The combination with a furnace body having a plurality of spaced tiebolt holes, of an annular radiator seated on said body and having asmoke fine and a clean-out extension, said radiator communicating withthe combustion chamber of the furnace through a central opening, andhaving a plurality of tie bolt holesspaced to aline with the holes onsaid body with the radiator adjusted to different relations relative tothe body, and tie bolts extending from and engaging alined holes of saidbody and radiator, all coacting for the purpose specified.

In witness whereof I have hereunto set my hand and seal in the presenceof two witnesses.

GEORGE IV. HOWES.
